He's 968 fast-growing poplar is a fast-growing new variety cultivated by Henan Dahe Agricultural Technology Co., Ltd. It has the advantages of fast growth, strong insect resistance, good material, strong drought resistance and cold resistance, etc. It is a good material for making high-grade paper and plywood.
First, suitable conditions
Temperature: -32--40°C; Soil pH: pH 5.0--8.5.
Second, cultivation technology
1, choose seedlings. One-year-old seedlings, disease-free pests, strong and vigorous winter buds were selected for cuttings and treated with rooting powder.
2, site preparation. The nursery is suitable for the selection of sandy loam clay with relatively flat terrain, well-drained water, suitable irrigation conditions, and relatively loose soil. Turning the ground before the winter, Saki fertilizer, water leveling. Apply urea, diammonium-potassium fertilizer at the beginning of spring, then deep plowing.
3, do it. Every 1 meter doddle earthworms, sorghum 20 centimeters wide, 50 centimeters wide, with real or solid iron smashing shoots, seedlings for the nursery bed, the seedbed at both ends and the ditch connected.
4, cutting
(1) Density: 667 square meters (1 mu) of land is planted with 4,000 cuttings of seedlings, which can be spaced 30 centimeters by 50 centimeters or 40 centimeters by 40 centimeters.
(2) Operation method: Vertically insert into the soil. The first bud base above the insertion depth is equal to the soil surface, but the first bud cannot be buried in the soil. When cutting, use a string to position and seal the soil.
5. Seedling management
(1) When the buds are placed in contact with the agricultural film, the agricultural film is broken, and when the seedlings are deeply rooted, the agricultural film is removed, and the watering, loosening, and weeding are performed.
(2) According to the principle of retaining strength and weakening, the buds should be picked before the lateral branches are lignified, leaving only one plant. When the seedlings are higher than 1.5 meters, the upper buds are wiped off.
(3) Irrigation: Watering should be timely and appropriate, and the number of irrigations can be determined according to the local precipitation conditions, basically for 4-6 months, once a month for watering fertilizer, and 3 times a month for watering fertilizers from July to September. 667 square meters into the V before the chemical fertilizer 100 kg.
(4) Prevention of pests and diseases: Underground pests are controlled by adding 100% liquid of dipterex and wheat bran; leaf diseases can be sprayed with 1000 times of carbendazim.
6, cultivation techniques
(1) Lifting: When rooting, root loss should be minimized and lateral roots should be preserved.
(2) Fertilization and topdressing: fertilize 3-5 times a year. It is better to use farmyard fertilizer or compound fertilizer. Top dressing should be applied within 1.5 meters around the root.
(3) Pruning: The young trees are carried out after the fall of the leaves in winter each year. The branches and branches are removed and the scars are protected by mud brushing.
(4) Afforestation: The depth of afforestation should be 60-80 cm, and it should be densely filled with no gaps during afforestation.
(5) Planting form: It can be used for construction trees such as mountain forests, road forests, forestry intercroppings, farmland forests, and “four sides†greening. Planting density can be used 2 meters 3 meters, 3 meters 3 meters, 3 meters 4 meters and so on.
